2 Claims. 1

This invention relates to improvements in Wood planers. I

In applicants copending application, Serial No. 65,610, led December'16, 1948, for an Auxiliary Planer, there was described a planer designedfor use with a cabinet makers buzz planer, which made use of a feedroller and a dressing knife rotatably mounted in vertically adjustablebearings. It was subsequently found that by the incorporation of certainimprovements, the original planer could be used as a separate unit inthe accomplishment of many other Wood forming operations than originallyintended, the improvements being the subject of this application.

It is an object of this invention to provide a rugged but readilytransportable planer requiring neither a feed roller nor adjustablebearings and in which vibration has been reduced to a minimum.

A further object is the creation of a wood planer suitable for the homeand work Shop at a substantial saving in capital investment as 'cemparedwith that required for similar devices.

Other objects of the instant invention will be come apparent in thecourse of the following specification.

In the attainment of these objectives, the planer is constituted of abase supporting a horizontal work platform on which the wood isprocessed. At the back of the base` and over the work platform is avertically adjustable tool carrier. In the tool carrier, a dressing toolis rotatably mounted transversely of the work platform and is equippedwith adjustably mounted knife blades. Through an opening inthe top ofthe carrier, the shavings .are expelled by de#- flectors coacting withthe dressing tool and the opening. By placing the deflectors under.downa wardly directed tension, the wood to bevprocessed is convenientlyheld in position during the operation.

The invention will appear more clearly when taken in conjunction withthe accompanying drawings showing by way of example a preferredembodiment of the inventive idea.

In the drawings: Figure 1 is a front elevational view `of th planerconstructed in accordance with the prin ciples of this invention;

Figure 2 is a top plan view of the planer shown in Figure 1;

Figure 3 is a sectional View along 3--3 of Figure 2;

Figure 4 is a sectional view along 1164 of Figure 1;

Figure 5 is a view in'perspective of the dressing tool head; and

Figure 6 is a view in perspective of the molding tool head.

Referring nowin greater detail to the drawings where like referencenumerals indicate like parts, reference numeral I indicates the worktable assembly, II the dressing tool support, and I2 the tool carrieradjustable in the support II.

The work table assembly IB is constituted of a leg assembly I3 formedkof the two front legs I4 and I5 vand two similar back legs one of whichis shown in Figure 4. Between the tops of the 'front legs I4 and I5 isan integrally formed brace I6 (Fig. l) while similar braces extendbetween the corresponding front and back leg members at each end of theassembly. Between the back leg members is a brace Il eX- tendeddownwardly to the feet of the legs as illustrated in Figure 1 to give:strength` to the structure for the attachment of the later describeddressing tool support il. At the bottom of each leg is a right anglebracket I8 (Fig. l) through the upturned end of each of which is anopening for the insertion of a Screw i9 threaded into the leg whileA asimilar opening in the horizontal end provides a means for attaching theplaner to any desired support. On the back of the brace I'I isarearwardly extended protuberance 2li terminating in a vertical surface2l for the attachment of the dressing tool support II.

Over the upper edge of the leg assembly i3 is a horizontal work platform22 of rectangular shape except for an extension 23 (Fig. 4i) whichextends .rearwardly over the upper edge of the previously .mentionedprotuberance 26. Any suitable means may be used for attaching the workplatform 22 over the upper edge of the leg assembly.

At the bottom of the protuberance 2:3 is a pivot base 23 for the pivotalattachment of the dressing tool support II, the base 23 being attachedby the screws 2d. integrally formed with the base 23Y are two spacedvertical members, one of which is shown in Figure 4. cal member extendsabove the top of the base 23 and terminates in an ear 25 of arcuate formthrough which aligned openings are made for the insertion of the pivotpin l26 as later shown.

The dressing tool support II is constituted of the spaced parallel sidemembers 21 and 28 (Figs. 2 and 4) at the top vof whichis the integrallyor otherwise formed top member .25 extending forwardlyof'the sidemembers as most clearly shown in Figure 4. A bottom member 3l! isdisposed be- Each verti- Y 3 tween the bases of the side members. At thebottom, each side member is extended rearwardly and downwardly toprovide an ear 3| of arcuate form which coacts with the previouslymentioned ears 25 of the pivot base 23, openings being made in the ears3| aligned with the openings in the ears 25 through which the pivot pin26 is inserted so that the support I I can be rotated rearwardly fromthe position shown by the full lines in Figure 4 to the dotted lineposition. It will be noted that the front surfaces of the side members21 and 28 above the pivot base 23 bear against the vertical surface 2|of the protuberance 28 so that the weight of the superstructure isagainst that portion of the leg assembly |3 especially designed to carrythe weight. To adjust the position of the side members 21 and 28 in the'upright position relative to the vertical surface 2| similar screws 61are threaded throughY each side member above the ears 3|, the ends ofthe screws bearing against the Vertical surface 2|.

On the front of each side member 21 and 28 is a right angle member 32 soattached to the side members by the screws 33 as to provide the opposedrecesses 68 and 34 in which the later described slide 35 (Fig. 4) isadjustable.

The slide 35 is formed with recessed side edges which coact with thepreviously mentioned recesses 68 and 34 forming the slideway. Throughthe top of the slide 35 is a tap 38 formed along the vertical centerline thereof and through which the screw 31 is threaded, the top of thescrew 31 being rotatably passed through the top member 29 of the toolsupport and having keyed thereto at the top a handle member 38, thebottom of which is rotatably supported on the up'per surface of the toolsupport top member 29.

Extended forwardly of the slide 35 over the work platform 22 is the toolcarrier |2. The tool carrier |2 is a hollow container having a frontmember 39 spaced parallel from a back member 4G, the ends of the frontand back members being of arcuate form as shown in Figure 3. End membersof arcuate form are integrally formed between the front and back membersbut extend only partially down to the bottom edges thereof. The bottomof the carrier is open while over the upper edges of the front and backand end members is an integrally formed top member 4| on which is anupwardly directed protuberance 42 the back of which is in the plane ofthe back member 48. Taps are made in the back of the protuberance 42 forthe insertion of screws (not shown) first passed through alignedopenings in the slide 35 from the back and which support the toolcarrier i2. A transverse opening 43 in the top member 4| provides anoutlet for the shavings. In the front member 38 of the carrier there isa circular opening 46 and in the back member 40 an aligned opening 41.However, the opening 41 has a communicating opening or slot extendeddownwardly to the bottom of the back member 40 the width of which isgreater than the diameter of the later described driven shaft 48.Similar bearings 49 are inserted in each of the aligned openings for therotatable support of the driven shaft 48. On the inner surface of theback member 43 are the vertical slots or guideways 50 and open at thebottom and aligned with similar slots on the inner surface of thefront'rnember 38.

Within the carrier l2 and keyed to the shaft 48 or integrally formedtherewith is the square head dressing tool 51. Attached to each surfaceof the head is a knife blade 52 with the cutting edge 4 protrudingbeyond the edge o1' the surface to which it is attached.- Each knifeblade has formed along the edge opposite to the cutting edge a series ofspaced transverse slots which are aligned with taps formed on the headand through each slot a screw is threaded into a coacting tap whichmaintains the cuttings edge in any desired position relative to the edgeof the surface of the head on which it is mounted.

Also within the carrier I2 is the shaving deflector 44 of fiat surfaceexcept at the bottom where it turns inwardly as shown in Figure 3.Extended outwardly from each end of the deflector `44 is a pin 54coaeting with the previously mentioned vertical slots or guideways inthe back and front members 40 and 38 of the tool carrier and on the sideopposite the aforementioned opening 43. The deflector 44 is maintainedunder downwardly directed tension in the guideways by a spring 55 arounda screw 56 threaded in the top of the deiiector at each end and slidablethrough the top member 4|. The other deflector 45 along the outer edgeof the opening 43 is similar to the deector 44 except that the surfaceis entirely arcuate and extended inwardly as illustrated to coact withthe dressing tool and deflector 44 in expelling the shavings through theopening 43. A pin 54 in each end of the deector 45 slidable in thealigned slots or guideways is held by a ila-ngc 51a on the outer surfaceat each end of the deflector while maintaining the defiector underdownwardly directed tension in the slots are the screws 58 vinsertedthrough springs, similar to the previously mentioned springs 55, thescrews being slidable through the top member 4| and threaded intoaligned taps formed in a longitudinal rib 59 on the outer surface of thedeflector 45 at the top.

To lock the dressing tool 5| in position,` a bracket 60 (Fig. 1) ispivotally attached to the front of the leg assembly I3 by any pivotalmounting means 6|. By providing the bracket 68 with a closedlongitudinal slot 62 through which a screw actuated by a handle 63 isthreaded into a tap in the front member 330i the carrier l2, thesuperstructure of the planer is rigidly held on the base and vibrationmaterially lessened as compared with known devices of a like type.

The operation with the wood planer follows:

Suppose that the planer is in the position shown in Figure 1 and it isdesired to dress a piece of wood, dependent upon the thickness of thewood and the position of the tool carrier l2, the handle 63 isloosened'and the handle 38 rotated until one end of the wood can beinserted under the carrier with the end against one of the knife bladesand the side to be dressed uppermost. Then by rotating the handle 38,the carrier I2 is lowered until the deflector 45 bears against thesurface of the wood. If desired, by threading the screws 58 further intothe rib 58 the tension on the wood may be increased. After the bracket60 is fastened to the carrier |2 by threading the screw actuated by thehandle 63 into the coacting tap, the dressing tool 51 is set into motionby any suitable means (not shown) and the wood pressed forwardly of thedeector 45, the four knife blades assuring a finish that sanding couldhardly improve, the shaving deflectors not only eliminating wave orgouging of the material but providing suitable protection for theoperator, including the prevention of kick back.

Suppose further that it be desired to form a molding around a desk top,by removing the rear bearing 48 held in place by the lock ring 82a andthe set screw 63a as well as the set screw in the front bearing, theshaft 48 can be pulled rearwardly out of the front bearing, and out ofthe opening for the back bearing through the communicating opening. Byreversing the disassembly steps, another square head dressing tool 64 inwhich the taps 65 are made can be inserted in the tool carrier I 2. Anydesired type of molding blade (not shown) can be inserted in one of thetaps suitably positioned relative to the edge of the desk top. With thebracket 60 unlocked and pivoted downwardly out of the way, the desk topcan be guided over the platform 22 and under the molding blade toprovide an artistic edge for the desk which at present can only beaccomplished by using a separate strip of molding.
